I tested it now with a PIC12LF1572 and a clean setup with a new breakout board: At 1.8 V it needs 11.9 nA and at 3.3V it need 13.3 nA in sleep mode. The project file is updated. Maybe a new clean test setup helped as well, with only the microcontroller and a 100 nF capacitor between VDD and VSS:

Some more measurements with 3 V supply voltage:

- original code: 6.4 uA

- with brown-out reset disabled (#pragma config BOREN = OFF) it needs only 2.8 uA

No more ideas, waiting for an answer from Microchip support now.
